It will be quicker but I'm not sure how much. I love my Te-60. It makes good enough power for me. My combo:
Te-60/.63garrett, Mease Big neck 15 row Slic, Champion heads/intake, 206 roller, 60's, LS1 maf, T+/TT chip, Razor's alky, Janis transmission, 3-3200 5 disc Vigilante, 23psi, 23/23 timing on 93octane/alky. Best so far 11.25@121.62mph 1.73 60 converter unlocked.
With a better 60 and locking the converter it should go in the high 10's.
